Congenital rotary nystagmus associated with head turning successful surgical management.

congenital nystagmus is a rhythmic ocular oscillation usually in the horizontal plane which may be associated with a significant head turn, tilt, or tip to achieve maximal damping of eye movements and improved vision. Purely rotary congenital nystagmus associated with head turn is unusual. This report outlines findings in a case of congenital rotary nystagmus with a functionally significant 30-degree head turn and describes successful surgical management. Current management of patients with congenital mystagmus is discussed.
